Given the time, late in the day, and the unbalanced composition this painting had its challenges. In order to create subtle separation in the islands I relied on colour temperature and texture. Warm temperatures with texture advance in the picture plane. To create some balance I used some rocks and a few splashes of colours observed while on site. These do not show in my photo reference. So, emphasize them so the viewer will see them.
For this painting I used a #12 and #8 bristle filbert. The palette consisted of Ultramarine Blue, Viridian, Cadmium Lemon Yellow, Cadmium Orange, Alizarin, Mineral Violet and Titanium White. For earth tones I mix them. They are always richer than the tube colours.
